    Hi Pete,

    Comments:

    (1) RFC 2396 (in syntaxes) is obsoleted by RFC 3986.

    (2) I suggest that instead of 'Address' (somewhat inaccurate), the
        keyword for WS-Print Service URL be 'ServiceURI' - consistent with
        other existing channels and with the PWG Port Monitor MIB.

    (3) Syntax for DeviceUUID should be changed to
        'URI (Unicode UTF-8 per RFC 3986)'
        - consistent with other channels and RFC 4122 (your reference)
        - note that OCTET STRING is BINARY and illegal in human-readable
        prtChannelInfo object (which must be string parseable).

    Cheers,
    - Ira
